ALLENTON, MISSOURI.

FEED-CUTTER.

Application fi'led- July 26,

To all whom, it may concern:

Be it known that I, J on}: If. BnUNNnn, a citizen of the United States of America, and a resident of Allenton, in the county of St. Louis, in the State of Missouri, have invented certain new and useful Improve ments in Feed-Cutteraof which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming. a part of this specification.

My invention relates to feed cutters in which beets, carrots, turnips, and other vegetables are cut up or shredded to make suitable stock feed. Generally stated, an object of my invention is to provide such a cutter which shall be simple, sturdy, efiicient, and yet shall be inexpensive to construct. Another object of my invention is to provide a cutter of this type which is easily operated and 'which can be quickly assembled and disassembled.

\Vith the foregoing and other objects in view, the invention comprises the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention. However, it is to be understood that the invention comprehends changes, variations and modifications which come within the scope of the claims hereunto appended.

In the drawings, in which like numerals indicate like parts in all the views,

Figure I is a top plan View of the mechanism.

Fig. II is a front elevation.

Fig. III is a vertical section taken approximately on the line III-III, Fig. II.

Fig. IV is an enlarged fragmentary vertical section of the cutter disk.

A designates a supporting table upon which is mounted the cutting mechanism. 1 designates a cutter disk, preferably made of sheet metal and having numerous perforations 2 therein. This disk is fixed to a shaft 3, which is adapted to rotate in bearings 4 mounted on the table A. An operating handle 5,'by which the shaft and cutter disk may be manually driven, is connected to the outer end of the drive shaft 3, the operating handle having a hand-grip 5' thereon. The bearings 41 and the shaft 3 need not be of metal, for I have found that Specification of Letters-Patent. Patented Je ly 12'; 1921,

1920. SerialfNo. 398,953.

good results are obtained when .they are made of wood.

A feed'trough 6' is mounted on the'table and is inclined downwardly toward the cutter disk, the material to be cutbeing fed against the cutterdisk with one hand while the handleisrotated with the other hand.

The metal. at only one side of. eaclr of the perforations 2 is bent outwardly from the plane of the inner surface 7 of the disk,.so as toprovideshort inclined teeth 9 adapted to shred or slicethe material throughthe perforations. 1

As the beetsor other vegetables are forced against the cutter, there is a pressure or thrust exerted axially of the disk, tending to bend or bow the flexible disk outwardly about its axis. To overcome this bowing tendency, I, have provided athrust roller 8 adapted to bear against the outer surface of the disk 1 at a point near the discharge end of the feed trough 6. This thrust roller 8 l maybe rubber tired if desired, so that it will not wear a groove in the disk 1, and is freely mounted so as to be rotatable on a rod 10, which in turn is supported in notches 11 and 12 in supporting arms 11 and 12, said supporting arms being secured to said table and spaced substantially diametrically of said disk. The ends of the rod 10 need not have a complete circumferential contact in the supporting arms 11 and 12, but should merely rest in the grooves therein, for there will be no tendency for the rod to lift from the supports, as the thrust transmitted to the rod 10 through the roller 8 will be downwardly upon the supports.

Another advantage of this type of support is that, in disassembling the cutter, no bolts or screws need be removed, for the rod and roller may be simply lifted from its supports. To prevent the rod 10 from being displaced in operation, one of the ends, 13

Q periphery of the disk, and secured at its ends to the table. A wear plate 16 maybe interposed between the table and the cutter disk 1. A machine of the character described comprising a shaft, a. perforated cutter disk mounted on said shaft and secured thereto,

" supporting bearings at one end of said shaft,

an operating handle at the other end of said shaft, a rod extending across the face of said cutter disk adjacent thereto, a thrust roller rotatably mounted on saidrod and adapted to bear against said perforated cutter disk, and means whereby said rod is removably supported;

2. A machine of the character described comprising a shaft, a perforated cutter disk mounted on said shaft and secured thereto,

supporting bearings at one end of said shaft, an operating handle at the other end of said shaft, a rod extending across the face of said cutter disk, a thrust roller rotatably mounted on said rod and bearing against said perforated cutter disk, and notched members for removably supporting said rod.

3. A machine of the character described comprising a shaft, a perforated cutter disk mounted on said shaft and fixed thereto, supporting bearings at one end of said shaft,

shaft, a rod eXtending diagonally across the face of said perforated cutter disk, a thrust roller rotatably mounted on said diagonal rod and bearmg against said perforated cut an operating handle at the other end of said ter disk, said handle, thrust roller and diagonal rodbeing located at one side of said disk and said bearings being at the other side of the disk, and supporting members provided with notches open at the top in which said diagonal rod is removably mounted, one end of said rod being bent downwardly to engage one of the notched members to retain said rod in said notched members,

In testimony that I claim the foregoing I hereunto affix my signature.

JOHN H. BRUNNER.
